The Peninsula Spa & Wellness Center

"The spa is high up on the 19th and 20th floors of the hotel, and the treatments are beyond-pampering and impressively corrective. The Cryo 3R Facial uses chilled air to regenerate skin and support collagen (you look remarkably glowy immediately after), while the European Deep Cleansing Facial involves a revitalizing massage, thorough pore detoxification, and layer upon layer of nourishing serums and creams. There's a eucalyptus steam room, as well as a relaxation room where you can curl up next to a fireplace. The facials can absolutely stand alone, but if you're splurging, consider one of the famous half- or full-day spa journeys."
